采用快冻法测定了高性能混凝土(High Performance Concrete,HPC)在水、浓度为3.5％的NaCl除冰盐、3.5％～25％的醋酸钙镁(Calcium magnesium acetate,CMA,机场道面除冰液)、25％的乙二醇(飞机除冰液)和商品飞机除冰液中的抗冻性.结果表明,在3.5％ CMA溶液中,HPC抗冻性比水中冻融提高了1.09倍,其冻融破坏特征与水中冻融一样,均属于内部微裂纹扩展,完全不同于HPC在3.5％ NaCl溶液中的盐冻表面剥蚀.在浓度为25％的条件下,CMA机场道面除冰液对HPC无冻融破坏作用,而乙二醇飞机除冰液、尤其是商品飞机除冰液对HPC有明显的冻融破坏作用.因此,CMA机场道面除冰液能够有效地延缓HPC的冻融破坏.
